The steemdollar varied between 1.30 and .75 USD and now ~ 1 USD. However the steem rose from .18 to +3.00 and now to 0.13.

ok... now I get it from where you took this 0.13. On daily basis I track only market cap, which is better indicator for me, because I am SP holder

On the internal market, Bittrex and Poloniex
